Watch the whole game from the deal

The seed + command log has been the whole game all along; now it can
be watched. Finished games offer "⟲ Watch the whole game" beside the
face-up hands: the server replays every command from seq 0 through
the same redacted catch-up pipeline (the 200-step window remains a
live-game courtesy; full replays wait for the game to finish), and
the reel plays it titled "The whole tale, from the deal" with new
1×/2×/4× speed controls for the long tellings. Each viewer rewatches
from their own seat — hidden information stays hidden in the retelling
exactly as it was at the table.
